SLED-PROPELLER.

SPECIFICATION forming part of Letters Patent N0. 314,210, daced March1'7, 1885. Applieation filed June 24.1884. (X0 model.)

T0 all whom it may concern:

Be it known thao I, JOSEPH WISSEN, a residem: of bhe city of Decatur,counb'y of Macon, and State of Illinois, have invented certain new anduseful Improvementsdn Sled-Propel- 1ers, of whieh the following is aspeeifieation.

In the drawings accompanying and forming a part 0f this specificataion,Figure 1 is a perspective view 0f a sled with my device alstached. Fig.2 represents the handle, and Fig. 3 shows the propeller insideelevation.

A is the sled, which may be formed in any suitable manner.

a is a lever, provided with bearings a a the handle.

b represents a eogged segmenb formed of the lower termination of 1evera. V

c is a smaller cogged segment; adapted t0 gear with b, and provided withlever-terminatiou d.

e isa bar hinged t0 1ever d.

f is a bar hinged to lever e and provided with recepoacle y andSet-serew k.

h is a pointed bar adapted 130 be adj usted in reeeptaele g.

e is ah extension 011 bar e thab limits the upward swinging motion ofbar f;

m represents the handle, provided .with knobs n n am]. diminished.bearings 0 o.

10 shows the braekeb by which the ropelling deviee is attached andsup1oorted.

q is a pin insertedin the sled-frame for the purpose of limiting theupward motion of 1ever d.

l l represent securing-bolts for levers a and d.

In Fig. 1 my deviee is shown ready for a propelling-stroke, and in Fig.2 the relation of the vatious parts is shown ab the completion of aStroke.

The propelling is effeeted by oscillating the levers a,and the ower isconveyed to ohe penetrating points through b c d e f in the order named.

A propelling device is attached 120 each side of the s1ed by means ofbrackets p, and a han dle, m, eonneets tzhe 1evers a and provides asuitalole hand hold for 'ohe operator.

T0 inerease the speed of the sled without increasing the mooion of t-heoperator, handle for m is plaeed in holes a 0f the levers a, therebyshortening the leverage.

T0 ehange the position of the handle with relabion 120 the sled for tshepurpose of modifying 1she osition of the operator while oseillating thelevers, ab'aehingbolts l Z may be 5 5 drawn and the relative position ofthe gearing b c be adj usted as desired.

The handle m is provided with diminished bearings o o, that work soloosely in holes a a that; one lever may be operated wiohout affectingthe other.

Lever d and bar e are so hinged that t-he smallest; angle possible forthem to form is shown in Fig. l.

Projection e, as before stated, is relied on 130 limit the-upward Swing0f bar f, and 0011- sequently whenever the device is in the positionindicaoed in Fig. l points h are held firmly againsb the ground 0r ice.

Points h may loe adjusted in head g, and may also be removed forsharpening 01 other purposes. v

'Ihe levers are oscillated by the oceupant 01 the sled, and in turningeither 1ever may be operated, to the exclusion of t-he other.

In sled-propelling devices heretofore produced it has been necessary tokeep the mechanism in swift mobion in order 130 attain 130 anyconsiderable degree of speed, thereby effecbing with great labor whatshould. be effected wlth ease, as it is observable that of alleonveyances a sled on snow well beaten er 0n ice requires the leastpower 110 propel.

In my device, owing 150 the peculiarilsy of the gearing, a slow steadymotion will propel the sled rapidly, and the manner of applying thepowerwhich consists in pulling back with a motion similar to rowing,provides a beneficial exereise for the entire body.

I claim as new and desire 130 secure by Let- 0 ters Patentl. Thecombination, in a sled-propelling device, by means of whicl1 a slowsteady backward mobion similar to rowing is used 110 impart motion tothe sled, of levers a, geared segments b and c, levers d, and suitablemeans for connecting the said levers d wibh enetrating points h, as andfor the purpose sei: forth.
